So, I'm a bit confused.

When I did quick freedom, I believe it mentioned something about firmware 2.2.1. When 3.0 comes out, will the custom firmware be made for the differences whether it be settings or graphically or whatever? Or will they have to come out with a new JB? I don't really know much about JB firmware.

the exploit that makes the ipod able to be untethered is in the hardware. any new firmwares that come out will have no effect on the exploit, since u can't patch a hardware issue with a software update. so when 3.0 comes out, there will b a jailbreak relativly shortly after the release.. ur ok...
